KappaElastin, a pure soluble protein was developed by a group of medical researchers working at the CNRS, a major European scientific and medical research center, consists of peptides with molecular weight included between 10 000 and 70 000 derived by partial hydrolysis of cross-linked elastin.

KappaElastin has the same composition as the elastin molecule in the human body, especially the amino-acids Desmosin-Isodesmosin cross linkup.

KappaElastin is the complete active molecule of elastin and the only one able to regenerate, renew and increase the level of natural elastin in our skin.

It is soluble in aqueous and organic media and can therefore be incorporated into cosmetic preparations due to its very small molecular weight and its compatibility with lipophylic solvents.

Elastin vs KappaElastin molecule

As there are strong hydrophobic interactions between KappaElastin peptides in an aqueous medium, at 37°C, KappaElastin coacervates* at the physiological PH of the skin.

When applied daily, KappaElastin stimulates the production of elastin. It covers the skin with a fine protective layer and its action inhibits the skin’s aging process.
